Changing which files open in Protected View
2 If the red Protected View message bar appears when you open a
document, the document did not pass a validation process that
Office applies to every file you open. This can occur if the file is
damaged by a hardware or software problem or it was modified for
a malicious purpose. If the file is suspicious or unknown, the best
action is to close the document and delete it from your computer. If
you know the document’s creator, request another copy of the file.
If you decide to try to edit the document despite the warning, click
File to display the Info tab of the Backstage view, and then click Edit
TIP If you click Edit Anyway to open a damaged document,
the document might still fail to open. The behavior depends on

TIP It’s a good idea to keep the check box selected for Enable
Protected View For Files Located In Potentially Unsafe Loca-

Files folder, from which you can’t be sure of a file’s history.
TIP When you click the Enable Editing button on the message
bar to allow editing of a document, that document automati-
cally becomes trusted. When you open the same document in the
future, it won’t open in Protected View.
